NASA apots Typhoon Songda's cloud-filled eye


Small but powerful Typhoon Songda continued moving to the northeast and over the open ocean of the Northwestern Pacific Ocean when NASA's Terra satellite passed overhead and saw its cloud-filled eye.

Tropical storm Songda, the twenty-third tropical cyclone of the northwestern Pacific Ocean formed on Oct. 9. At 5 a.m. EDT (0900 UTC) Songda was located about 488 miles east-southeast of Iwo To island, Japan.

On Oct. 10 at 8:45 p.m. EDT (Oct. 11 at 00:45 UTC) NASA's Terra satellite saw powerful thunderstorms circling Typhoon Songda's cloud-filled eye. Stronger storms appeared a brighter white than those storms surrounding the center.

On Oct. 10 at 8:45 p.m. EDT (Oct. 11 at 00:45 UTC) The Moderate Resolution Imaging= Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible-light image of Songda. MODIS saw powerful thunderstorms circling Typhoon Songda's 20 nautical mile wide, cloud-filled eye. Stronger storms appeared a brighter white than those storms surrounding the center.

On Oct. 11 at 11 a.m. EDT (1500 UTC) Typhoon Songda's maximum sustained winds were near 100 knots (115.1 mph/185.2 kph).

Hurricane-force winds were occurring up to 30 miles from the center, while tropical storm force winds extended just 90 miles. Sondga is a compact storm.

It was located far from land areas and about 538 nautical miles southeast of Yokosaka, Japan near 29.3 degrees north latitude and 147.6 degrees east longitude. Songda was moving to the northeast at (11.5 mph/18.5 kph).

The Joint Typhoon Warning Center forecast noted increasing vertical wind shear and cooling sea surface temperatures will rapidly erode the system. Songda is forecast to begin weakening and become extra-tropical over the next two days.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Im Focus: Mars' oceans formed early, possibly aided by massive volcanic eruptions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
